Bug in gpg 1.2.2-rc1-SuSE with --passphrase-fd 0?

Is this a bug or a feature with gpg 1.2.2-rc1-SuSE from SuSE 8.2? If I try the command below I am asked for a mantra/password. echo "Testpw" | gpg --batch --passphrase-fd 0 \ --output test.txt.gpg --symmetric test.txt In a German usenet-discussion I was told in MID that the command works with a "non-SuSE-modified gpg" Do you have any ideas what I have to do to use gpg in a script with a dynamically created password?
